Error at the "Database Launch" step in the Example STRANDS System Page

Hello!
I'm trying to test the examples available at the "Example STRANDS System Page". I get the following error:

CMD:
roslaunch mongodb_store mongodb_store.launch db_path:='path to my db_dir'/strands_sim_example

ERROR:
Traceback (most recent call last):
File "/opt/ros/indigo/lib/mongodb_store/message_store_node.py", line 21, in

Thanks for trying our code!
This is a known current issue: strands-project/mongodb_store#182
If you install mongodb_store from source it goes away, but we're still looking for a proper fix.
